the water receptacle is filled to a point above the bottom of Atheclothes receptacle whereby the releasing device is immersed. When thewater begins to 'boil it will follow the steam up the space between thetjworeceptacles, and said hot water/and steam Wijll,be projected throughthe; perforations onr to the clothesgf f Ther top of 4the' clothesreceptacle is open' and thewater fromthe jets will accumulate' in theclothes receptacle.v -As the' water in the'water receptacleboils` krup"acertain pressure is exerted on the valve .or upon the end ofthe trapmember` as the case maybe, and a sufiicien't amount of water Vmust Abeaccumulated in the clothesA receptacle before this 'pressure-isovercome.

"Theparts 17, 18 andV1 9 constitute a releasing device and, form a trap for holding water:in the 5 clothes receptacle until it is released.l The releasing ,de-

Vvice y permits of considerable variation in structure.

" In operating the wash' boiler water is placed in the receptacle 3until it covers the bottom -15 of theclothes receptacle as .indicated bythe water line. o Soap or otherwashing agents yis placed in the boilerand .the clothes to be washed `are vthendeposited in the receptacle 6.Heat is appliedunderfthe water receptacle and within the casing 1 andthe water caused to boil and the soap dissolved. The water at the `lowerend of the space`12 will boil first and a proportion of steam will begenerated with theresult that said steam and water rise in the space 12as "the boiling continues. The steamv and hot water willy firstbeprojectedfthrough the .perforations 14, but as the boiling increasesthesteam and .water 'will rise in the space 12 projected throughtheperforations 13 with great intensity or force,v all of said jetsconverging toward the center ofthe clothes ,receptacle "and` formiiflsVSpray which acts lo'n the'clothes and spurts throughthe fabric ofthesame with considerzdile'force,v

A sthe Vwater boils av certain pressure will be exerted on the open endlof ktheelbow 19 andfthus no'water will p assfrom the clothes receptacledown" through thepartsl? and 1S until sufficient ,water has been accumu-121t1 .ie the Clothes me'ptile119,0 Qvercqme vthe saidpressure. VWhenthe pressure is overcome'and the waterfreleased the actioniivltbeisuddn. Up. to the `time this relaas* ing action'takes place thejets Will continue and their intensity gradually increases; however thethe water in the clothes receptacle 'is released `the jets cease and as.the water is precipitated or rushes from the yreceptacle 6 down throughthe parts 17 and beginsftoboil yup and is againfprojectedin jets. Thisaction is again'followed-bythe releasing action and the yopera-tioncontinues as long'as'fthe heat is maintained and sutiicient wateryremains f in the receptacles.

1 As stated the releasing device permits of y varied construction solong as afdepending pipe Aor tubular member is'us'ed and this inventioncontemplates the use of a depending pipeor tubular memberin all itsl'forms'. As illustrating one of 'the variations a modified form"of-releasing deviceis show-n inFigs. 3 and 1. Allth'e parts are thesame asin Figs 11and2 with theexception of `the 'omission ofthe partslSand 19. An elbow 20 is attachedto lthe lower end ofthe member 117, andthe lateral end of the elbowterminatesin a flared mouth 21 covered ilpyascreen 2 2 and containing a ball valve23.

Pressure .acting on the valve 2 3 seatsthe-sarne against the en'd of theelbow and'obstruets the downward flow of water through said elbow.Whenthe weight of the water -in `the clothes receptacle andy the partsHand 20 is suiicient to overcome tlie`pressurethe ball is dislodged androlls downl against the screen .,22, whereby the water iisY` released.lill-he vflaring mouth provides an area over which the pressure mayactlaterally in seating the valve. y

The foregoing description and illustration clearly expressthe'invention, but itis to beunderstood .that said: illustrationpismerelyan exemplification and the invention may be carried yout invarious other ways.

1. In a wash boilen' a water receptacle, a clothes receptacle mounted inthe, waterv receptacle and having its bottom somel dis- Vtance above thebottom Vor the water recep-Z t'acle,y .whereby a water reservoir isr ro-,vided below 'the clothes receptacle, the

clothes receptacle'being slightly's'pa ed l from they water receptacle;Ywhereby 7 af vertical s' ace'is provided between'the receptaclesfapreservoir formed between the bottoms of the two receptacles.

2. In a wash boiler, a cylindrical water receptacle having an internalprojection near its upper end, a supporting casing sur,- rounding thelower portion of the water receptacle, a gasket mounted on theprojection within the upper end of the water receptacle, a cylindricalclothes receptacle having its upper ends resting on the gasket withinthe water receptacle, means mounted on the water receptacle for clampingthe upper end ofthe clothes receptacle on the gasket whereby steamtight-joint is had, the clothes receptacle being slightly spaced fromthe water receptacle to form an annular vertical space therebetweenclosed by the steamtight joint at its upper end, the clothes receptaclehaving a' plurality of minute per- Eorations grouped together at theupper end of the space between the receptacles, an opening in the bottomof the clothes receptacle, and a tubular water holding andreleasingkmember dependingvfrom the opening and having a laterallydirected discharge opening below the bottom of the clothes receptacle. p
